Now my plots work well. Just I have a few more questions to clarify some confusion.</div><div><br></div><div>1) In my data, I do not have any data over the ocean. I noticed that there is strong interpolation over ocean in the figure (see any figure attached), which are not necessary. It seems that I could use resources.<a href="http://www.ncl.ucar.edu/Document/Graphics/Resources/mp.shtml#mpGridMaskMode" style="line-height: 1.3;"><em style="font-weight: 700;">mpGridMaskMode</em></a> = "MaskOcean » , but it seems not working.</div><div> PS: I prefer that ocean would be white color for example. What shall I do ?</div><div><br></div><div>2) Over small islands, the interpolation method also produced some effects (see large yellow areas on the ocean in figure isccp_19V.00001.png). Again I do not need the ocean around the island, just the results over (small) islands.</div><div><br></div><div>3) I would like to increase the figure size of figure. I tried :</div><div><div>resources.vpXF = 0.1 # Change the size and location of the</div><div> resources.vpYF = 0.9 # plot on the viewport.</div><div> resources.vpWidthF = 0.4</div><div> resources.vpHeightF = 0.8</div></div><div><br></div><div>But when I open the figure, it remains the same size, seems to me.</div><div><br></div><div>4) I would like to put the larger values in color red, and small values in blue for example. (Now it is the inverse). How to modify it ?</div><div><br></div><div>5) Yes, indeed I have several figures to plot. I found that they are named as isccp.000001.png for example. Could I name it as isccp.model.png ?</div><div> In my code, I will loop over several files (current figures from only do 1-time iteration). Do I have to clear something after each iteration is finished ? Actually it does not work for more than 1 iteration (message Invalid workstation).</div><div><br></div><div> I attach the code and also a few figures to you. Thank you in advance for your help !</div><div><br></div><div>Best wishes,</div><div><br></div><div>Xiaoni</div><div><br></div><div></div></body></html>
